Example 1:

As shown in FIG. 1 , the present invention provides a washing machine cover with double-sided touch display, including a cover body 1 , a double-sided operable touch button 2 is arranged inside the cover body 1 , and touch buttons 2 are arranged on the front and back of the cover body. The cover body 1 is also provided with a first light source 4, and the cover body 1 is provided with light guides 3 on the front and back of the touch key 2 respectively. The light guide bodies guide the light of the first light source to the touch area.

First of all, the double-sided touch of the washing machine cover is realized by using the touch button 2, so that the washing machine cover can be operated by the user in both the closed state and the open state, thereby improving the operability of the washing machine cover and improving the user's understanding of the washing machine. The use experience of the washing machine; secondly, the light guide 3 is used to guide and diverge the light of the first light source 4, and the first light source 4 is distributed around the touch key 2 and emits light toward the light guide 3, so the first light source 4 is distributed around the touch button 2 and emits light toward the light guide 3. A light-emitting source 4 can be set to overlap with the touch key 2 or the light guide 3, that is, the setting of the first light source 4 will not increase the overall thickness. The thickness of the cover 1 is determined by the thickness of the touch key 2 and the two light guides 3. Therefore, the thickness of the cover body 1 can be prevented from being too large, the weight of the cover body 1 can be reduced, it is convenient for users to open or close, and it is convenient for users to use; Conducting light-guiding divergence, a small amount of the first light-emitting source 4 can be used to achieve a large-area lighting effect, which not only reduces the cost of the first light-emitting source 4, but also the display information on the cover of the washing machine can be enlarged and easier to see clearly, which is beneficial to User observation identification.

In this embodiment, the light guide body 3 is arranged perpendicular to the touch key 2 , the first light sources 4 are distributed around the touch key 2 , and the first light source 4 emits light toward the light guide body 3 . The first light-emitting source 4 is distributed around the touch key 2 and emits light toward the light guide 3, instead of letting the first light-emitting source 4 emit light directly toward the front or back of the cover 1, the light can be fully diffused and a small amount of light can be diffused. The first light source 4 forms a soft and uniform backlight effect, and the user does not feel dazzling when viewing the cover of the washing machine, which improves the user's use experience.

In order to make the overall thickness of the cover body 1 smaller, the touch keys 2 are integrated into the flexible printed circuit board 5. Specifically, the touch keys 2 can be formed by printing with non-transparent silver paste. The thickness of the flexible printed circuit board 5 is very small. The light source 4 is arranged on the front and back of the flexible printed circuit board 5, so that the front display and the back display are independent of each other and do not interfere with each other. Since only one first light-emitting source 4 can be arranged around a touch key 2, in order to effectively utilize the light of the first light-emitting source 4, the first light-emitting source 4 emits light toward the side wall of the light guide body 3, and the light is guided through the light guide. The refraction and diffuse reflection of the body 3 allow the light to be emitted uniformly from the end face of the light guide body 3 away from the touch key 2 . In this embodiment, in order to further improve the uniform light effect of the light guide body 3 , the first light source 4 is vertically attached to the side wall of the light guide body 3 and emits light toward the center of the light guide body 3 .

The first light source 4 can use LEDs, and the number can be changed according to needs, for example, one, two or more are provided. Since there are light guides 3, generally only one or two need to be provided, unless a larger area is required. The displayed information of the device generates a backlight effect, and the number of the first light-emitting sources 4 can be appropriately increased. In this embodiment, two first light-emitting sources 4 are arranged around each touch key 2. In order to allow the light guide 3 to better radiate the light of the first light-emitting source 4, avoid local highlights and cause display Non-uniform, the two first light sources 4 are arranged face to face. It can be understood that if multiple first light sources 4 are arranged around each touch key 2 , the multiple first light sources 4 should be evenly distributed around the touch key 2 .

Since the washing machine needs to implement many functions, there will be multiple touch buttons 2, so the light guide body 3 of each touch button 2 and the light guide body 3 of the other touch buttons 2 are separated by the light shielding body 6 to ensure that each The first light source 4 around each touch key 2 only diffuses light through the light guide body 3 of the touch key 2, which is more reliable and effective.

In order for the user to identify the function corresponding to each touch key 2, a structure for displaying information is provided on the cover of the washing machine. In this embodiment, the front and back of the cover body 1 are respectively provided with light-transmitting plates 7. The light-transmitting plates 7 can increase the strength of the washing machine cover and improve the integrity of the washing machine cover, which is beneficial to increase the aesthetics, so it can be An opaque layer for forming display information is provided on the light-transmitting plate 7 . The opaque layer can be formed by spraying or by sticking. The text, pattern, etc. to be displayed can be hollowed out on the opaque layer, or the text, pattern, etc. to be displayed can be set on the opaque layer, and a certain amount of light transmission can be set around the opaque layer. area to achieve backlight highlighting of displayed information.

It can be understood that in the case of meeting the strength requirements, the light guide body 3 and the light shielding body 6 can also be fixed as a whole by sticking a film, and the end face of the light guide body 3 away from the touch button 2 is provided with a display information. In this way, the overall thickness of the cover body 1 can be further reduced.

Embodiment 2:

As shown in FIG. 2 , the touch key 2 is integrated on the flexible printed circuit board 5, and the touch key is formed by printing with transparent silver paste. On the front or back of the board, since the touch keys are transparent, the light emitted by the first light source 4 can pass through the touch keys, thereby reducing the number of the first light sources 4 and reducing the cost.

For other undescribed contents, reference may be made to Embodiment 1.

Embodiment three:

As shown in FIG. 3 and FIG. 4 , on the basis of the above-mentioned embodiment, a second light-emitting source 8 composed of a seven-segment digital tube can be added to display information such as numbers, so as to facilitate users to observe content such as time and water volume. In this embodiment, , the cover body 1 is provided with a second light-emitting source 8 composed of a seven-segment digital tube. After the washing machine cover is changed between the open state and the closed state, the light-emitting state of the second light-emitting source is symmetrical with respect to the second light-emitting source in the middle position. transform. The seven-segment digital tubular structure composed of the second light source 8 can be set as required, generally two are set, and the maximum number is displayed as 99. It can also be used to display two letters or one number and letter, which can meet the general display purpose. The second light-emitting source may use LEDs.
